ma fliwwmew win/5555s In Figfiihe pisten a is eonstently eo tifined in a cylinder 0 'formel in .the mandrel fengages'a. stem 7L which has :1 series of straight splines 7/ The latter are slideble' in a correspondingly formed nut an of the plunger (5., The rearward encl of the s'Eezn 1 2, is connected. with e spindle Z freely rotate ole in the enfi 0f the slide so The spindle Z with stem, plunger, mandrel roci and blank is rotated between attacks at the rolls upon the blank in an ordinary manner by means of a toothed Wheel gearing t and interposed spring 0. i

I claim as my invention:

1. In a relling mill of the type describe cl a. feed slide, a mandrel rod supported thereby, a brake piston on said mandrel rod, 2;, member carried by said feed slide and held against longitudinal. displacement there on but in sliding engagement with said brake piston and means operative through ,seid

sliding engagement for intermittently rofmting the mandrel rod, subseentiaily as de- SCIllOGd.

2. In rolling mill of the type described, :i iced shale, i i-mandrel rocl support-ed there by, a, brake piston on said mandrel. rm, member carried by said feed slide and hei aga nst longitudinal displacement thereon, but hevlng a threaded engagement Wlilli said brake piston for rotating the letter on "the- .but having a threaded engagement with seici brake piston for rotating the letter on the longitudinal displacement thereof, tag-ether with a ratchet mechanism for holding said. threaded member against rotation in one direction.
